I think this is the biggest risk for any entrepreneur, to fail to recognize when an idea won't fly.
I've been guilty of this myself at times and I think the reason why this happens is based in having invested X in a project already. If X is already in it then you're going to do that little bit more to see if you can get it to work that way. So, now it's X+a little bit more, and so on.
The longer you 'hang in there' the harder it gets to throw it out.
So, the conclusion of this is: Do your thinking before you invest significant resources in to a project. Test the waters while you can still walk away. Then find something that gets traction, preferably without you pushing it.
